depending on what yearm what model and what condition.... you can get one for around $300 to $3,000... if its a non turbo i wouldnt spend more than $1000 if it needs some work... check out the car see if its a 2 seater or a 2+2. the 2 seater in my opinion looks better.. look for rust.. with some work you can build a car that will definatly turn some heads... ive owned my Z for over 15 years and about 5 years ago i started to restore it... its my favorite car... check it out
cut and paste it if the link dont work
